我今天咬紧牙关，决定从 Ubuntu 20.04 升级到 20.10，但在最后收到了“失败”消息。
启动后，我进入终端，执行了sudo apt updateand sudo apt upgrade，结果得到了以下信息，这对我来说意义不大。如果可能的话，我希望有一个解决方法，因为我的默认解决方案是简单地进行全新安装！

现在编辑并添加我现在已尝试运行 update-alternatives 的建议，但这给了我以下信息：
update-alternatives: error: /var/lib/dpkg/alternatives/mpi corrupt: slave link same as main link /usr/bin/mpicc
还根据要求，'cat /var/lib/dpkg/alternatives/mpi' 的输出

我在从 20.04.5 升级到 22.04.1 时遇到了这个问题。解决方法：
sudo rm -f /etc/alternatives/mpi* /var/lib/dpkg/alternatives/mpi*
sudo apt install openmpi-bin
